02Overview
What Iowa Speedway is like to drive.
The full circuit layout at Iowa Speedway is 1.12 miles with 5 corners worth setting up for and about 9 ft of elevation change. A generic track-day car in our model brakes hard 5 times a lap and is at full throttle for about 29% of the distance; the longest straight runs roughly 804 ft.
3 of the corners are slow (under 50 mph in the model), 2 are fast (over 75 mph). There are hairpins where exit speed matters more than entry. The corner notes below come from the mapped geometry, not from local knowledge; we’ll add a researched guide for Iowa Speedway later.

The speed trace is a model, not a real lap: a generic track-day car (about 1.1 g of cornering grip, 1 g braking, 150 W/kg) driven on the computed line through an assumed 12 m wide track. Use it to see where the braking zones and flat-out sections are, not to predict your speeds. Elevation: USGS 3DEP 1/3 arc-second (NED 10 m) via OpenTopoData, sampled every 25 m along the mapped centerline.
04Corner by corner
The corners at Iowa Speedway.
TRACK’s own corner numbering (C1, C2…), found from the curvature of the mapped centerline. It isn’t the official turn numbering. Each diagram shows the computed line: the minimum-curvature path through an assumed 12 m wide track. It’s a geometric starting point. Your instructor’s line comes first.
- C1
Fast left-hander
↰ LeftfastcornerTRACK numbering
A fast left-hand corner that turns about 34°, tightening to a radius of roughly 22 m (72 ft). The model car brakes for about 80 m (262 ft), from 112 to 81 mph. The computed line turns in from the right side, takes an apex close to the geometric apex, and lets the car run out to the right on exit.

Slow left-hander
↰ LeftslowchicaneTRACK numbering
A slow left-hand chicane that turns about 323°, tightening to a radius of roughly 17 m (56 ft). The model car brakes for about 130 m (427 ft), from 95 to 38 mph. The computed line turns in from the right side, takes an early apex, about 15 m before the geometric apex, and lets the car run out to the right on exit.

05Configurations
Every mapped loop at Iowa Speedway.
TRACK finds each closed loop in the OpenStreetMap raceway network. Named layouts come from OSM circuit relations; the rest are named by length, and some may be combinations the venue never runs. Your first session confirms which one you drove.

06Time it with TRACK
Drive Iowa Speedway. TRACK knows where you are.
No setup and no transponder. Start a session in the paddock and TRACK recognises Iowa Speedway and the layout from your GPS trace, then times every lap and sector with a live delta to your best.
- 1DetectTRACK matches your first few hundred metres against every mapped layout at Iowa Speedway, including shared pavement between configurations.
- 2Confirm the lineThe start/finish line here is estimated. When you’re stopped, TRACK shows it on the map: accept it or tap to move it. You’re never asked while driving.
- 3Laps, timed retroactivelyLaps you drove before confirming are timed from the recorded trace, so you don’t lose your first session.
- 4Go furtherSync a GoPro for video with telemetry and let TRACK Engineer point out where the time is. External 10–25 Hz GPS receivers for tighter sectors are awaiting hardware validation.
- Venue and layout detection is tested on simulated drives over real OpenStreetMap circuits, not yet in a real car. Compatible GPS receivers

FAQ
Iowa Speedway, answered.
How long is Iowa Speedway?
OpenStreetMap maps 2 closed loops at Iowa Speedway, from 0.89 mi to 1.12 mi (1.80 km). These are mapped centerline lengths; the venue’s published figures can differ slightly.
How much elevation change is there at Iowa Speedway?
About 9 ft (3 m) between the lowest and highest points of the full circuit layout, from USGS 3DEP elevation data sampled every 25 m. The steepest stretch is around 2%.
Which direction does Iowa Speedway run?
The main mapped layout runs counter-clockwise, from one-way tagging in OpenStreetMap. Check the event’s driver briefing: some venues run reverse-direction days.
Can I time laps at Iowa Speedway with my phone?
Yes, with the TRACK iPhone app (beta). It recognises Iowa Speedway and the layout you’re driving from GPS, then times laps and sectors. A phone’s GPS is good for lap times; an external 10–25 Hz receiver tightens sector splits.
Where is the start/finish line at Iowa Speedway?
TRACK estimates the line from the mapped geometry (usually beside the pit lane, or on the longest straight). It isn’t verified on site, so the app asks you to confirm or move it before timing your first session here.
How do I find track days at Iowa Speedway?
Clubs and organizers list HPDE, track days and club races on MotorsportReg. The venue’s own calendar (also linked) lists its events too. TRACK doesn’t list events itself.
Where can I stay near Iowa Speedway?
This page lists hotels, campgrounds, restaurants, fuel and parts stores near Iowa Speedway from OpenStreetMap, with straight-line distances. Book early for big event weekends.
